“…Only a nonwork-conserving protocol is capable of further restricting the CDV bound [6]. One important exception is when exclusively CBR VC's are multiplexed [17]. However, this simple case is not applicable to VBR traffic.…”

“…The lower bound has been proposed by ITU-T for terrestrial connections. A much stricter two-way delay bound (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) ms is required for voice calls using analog terminals, which includes 95 of all phones [2]. Longer delays generate significant talker echo due to impedance mismatches at the subscriber loop [5].…”

Abstract-A transmission and multiplexing strategy appropriate for voice over asynchronous transfer mode (ATM), called delayed frame queueing (DFQ), is proposed. This frame-based strategy has features in common with the synchronous transfer mode and is thus well suited to service synchronous applications such as voice, while retaining the statistical multiplexing capabilities of ATM. In particular, the DFQ service discipline can provide explicit and nontrivial bounds for queue delay and jitter, for both bursty as well as continuous traffic streams. Furthermore, the DFQ discipline can combine a wide range of delay and jitter bounds while also managing the distribution of quality of service violations among the traffic streams when congestion occurs. Jitter control is performed at the network periphery and thus does not negatively influence multiplexing gain at intermediate nodes. This efficient strategy has major implications in terms of the preferred alternatives chosen by clients when implementing source clock recovery for voice. DFQ allows the entire range of implementation alternatives for voice over ATM to be appropriately serviced, such as ATM adaptation layer types 1 and 2 (AAL1/2), adaptive playout, and immediate playout.

“…Mathematical models based on queuing theory, Markov analysis and using well-defined metrics such as throughput, response time, and utilization have been used in many network performance evaluations (Haverkort, 1998;Bolch, et al, 1998;Higginbottom, 1998). Other metrics utilized include network traffic performance (Adie, et al, 1998;Banerjee, et al, 1997), circuit overhead of switches Da Silva, et al, 1997), and equipment used and network conditions (Da Silva, et al, 1997).…”
